According to Messrs. Chan and Baker, the letter containing the suspicious substance was address to Times editorial page editor Andrew Rosenthal:
The address of The Times was hand-written and there was no return address. ‘There was a letter inside, but to the best of my knowledge, no one from The Times has read it,’ [Times spoksewoman Catherine J.] Mathis said, adding that the letter and envelope had been turned over to the police.
Mr. Rosenthal’s executive secretary opened the envelope, and a white powdery substance came out of it, the authorities said. The powder will be subjected to field tests and more in-depth follow-up tests, Mr. Browne said.
Messrs. Chan and Baker also report that, "The secretary and two other Times employees, including a mailroom worker, were being decontaminated as a precaution."
